Is Tap Water Safe to Drink in New Orleans?

Yes, tap water in New Orleans is treated to meet EPA standards day-to-day, but the city's aging power and pressure infrastructure has caused several boil-water advisories in recent years, so it's worth checking current status during your visit.

Water Source

The Sewerage and Water Board of New Orleans (SWBNO) draws from the Mississippi River, treating it before distribution across the city.

EPA Compliance Status

Meets federal Safe Drinking Water Act standards under normal operation; the system has issued repeated boil-water advisories in recent years tied to power outages and pressure loss rather than routine source-water contamination.

Notable Contaminants & Context

  • Aging turbine-based power infrastructure has caused pressure drops that trigger precautionary boil-water advisories, a well-documented recurring issue distinct from routine treated-water quality
  • No significant contamination concerns in day-to-day treated water

How It Compares

New Orleans's power and pressure infrastructure fragility is a distinct, well-documented issue from the underlying river-water treatment process itself, and the city has pursued infrastructure investment to reduce advisory frequency.

Tips

  • Check SWBNO's current advisory status if visiting, especially after storms or power disruptions
  • Day-to-day tap water is treated and safe
  • Bottled water is a reasonable backup to keep on hand during hurricane season
